SPECIFICATION forming part of Letters Patent No. 739,517, datedSeptember 22, 1903.

' Application filed March 24, 1903; Serial No. 149,369. 1N0 model.) I II To all whom it may concern.-

ful improvements in journal-boxes, and par-' ticularly to theconstruction of the lid therefor; and the particular object ofmyinvention is to provide a lid of the hinged type which will restfirmly on its seat all the way round and which will be held tightly tothe seat, whereby the lid will form a dust-tight cover for the box. Theform of lid'shown in this application is a modification of that shownand described in my application, Serial No. 142,609, filed February 9,1903.

With these objects in view the invention relates to certainconstructions and combinations of parts, the preferred form of whichwill be first particularly described and the invention pointed out'inclaims.

Referring to the drawings, wherein like parts are represented by thesame referencenumeral wherever they occur, Figure 1 is a side elevationof a journal-box, partlyin seetion, showing my lid applied thereto. Fig.2 is a front view of the box, partly in section. Fig. 3 is a detailedview of the spring which holds the lid either open or closed.

1 designates a journal-box of any desired type provided with the usualopening in its front, the opening having the seat 2 running round thesame, on which the lid 3 is adapted,

to rest.

4 4. are a pair of ears suitably spaced apart and preferablyformedintegral with the box.

I have shown these ears as extending up from bolt in place.

the ears on the box may be inside and those on the lid outside, ifpreferred.

'7 is a bolt passing'through the ears l and 5 and on which the lidswings. As shown, this bolt is provided at one end with a head 8 and atthe other end-with a slot through which the cotter-pin 9 is passed tohold the Pivoted on-the bolt between the ears 5 5 is an arm 10, the armor lever having a head 11, provided with an opening through which thebolt 7 passes, and this head is provided with a fiat portion 12. atelyin the rear of the head 11 I provide on the box a projection 13 ofproper shape to receive and hold the coil-spring 14. This spring iscomposed, preferably, as shown, of two coils 15, connected by a centraltongue '16, the free ends 17 of the wire forming this spring beingadapted .to enter holes in the rear portion of the projection 13, thecoils 15 of the spring 1 1 resting against the curved back portion 18 ofthe projection 13 and the tongue 16 hearing against the head 11 of thearm'lO. When the box is in the closed position,as shown in Fig.1,thetongue rests against flat portion 12 of the head 11, and when the.box is opened the spring will rest against the portion 19 of the headand hold the-lid raised. 20 is a lug provided nearthe centerof the cover3 within the area of the seat and under which the outer free end of thearm 10 enthat the spring 14 will holdthe lid?) to its seat when the boxis closed, as shown in Fig. 1, and will hold the lid up when the box isopened. Because of the elongated opening this lid is free to move towardand away from its seat Without interference by the pivot-bolt 7. Hencewhen the pressure is exerted on the cent-erof, the lid by the arm 10 thepressure will be equally distributed upon the seat all 'way round,and-this equal distribution of the and mechanical changes might be madelmmedie gages. .By this construction it will be seen.

therein without departing from the spirit of my invention.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-- 1. The combination with a journal-box ofa lid hinged to the box, an arm hinged to the box on the same pivot bywhich the lid is hinged, a spring mounted on the box and bearing at oneend on the arm and adapted to hold the lid to its seat, the pressure ofthe spring being exerted on the lid through the arm only at a pointWithin the area of the seat.

2. The combination with a journal-box, provided with a seat, of a lidhinged to the box, a lever pivoted on the box having one end bearing onthe lid within the area of the seat, a spring mounted on the box havingone end secured to the box and the other end bearing against the otherend of the lever.

3. The combination with a journal-box provided with a seat, of a lidhinged to the box, a lever pivoted on the box having one end bearing onthe lid Within the area of the seat, a coiled spring mounted on the boxhaving one end secured to the box and the other end bearing againsttheother end of the lever.

4:. The combination with a journal-box provided with a seat, of a lidhinged to the box, a lever pivoted on the box having one end bearing onthe lid Within the area of the seat, a double coiled spring connected bya central tongue, the disconnected ends of the spring being secured tothe box and tongue of the spring being adapted to bear against the otherend'of the lever.

Signed by me at Baltimore, Maryland, this 17th day of March, 1903.
